Microservices – Definition

An architectural approach where applications are built as a collection of small, independent services that communicate through APIs.

Microservices architecture enables organizations to develop, deploy, and scale services independently. This approach improves agility, scalability, and resilience in complex e-commerce environments. The core benefit is fault isolation: if the recommendation service experiences an outage in a microservices architecture, checkout and product browsing can continue functioning normally, whereas in a monolithic system, a failure in one part of the application can bring down the entire platform. This resilience comes at the cost of operational complexity — teams need to manage service discovery, network latency between services, distributed monitoring, and versioning across many independently deployed components. Salesforce Commerce Cloud itself isn't a pure microservices platform in the strict sense — it's a multi-tenant SaaS platform with its own internal architecture — but the broader trend toward composable commerce, where retailers combine SFCC with separately deployed services for search, personalization, or content, follows microservices principles at the level of the overall technology stack.
